Hello, how would I go about binding different implementations based on an environment variable?

[nwh]

Something like this?

single<ServiceInterface> {
  if (System.getenv("...") == ...) ServiceImpl1() else ServiceImpl2()
}

[psh]

We inject the environment variable as a BuildConfig field in our Android code, then use it to optionally include different modules -

object NetworkingKoinConfig {
    val modules = listOf(
        apiErrorModule,
        okHttpModule,
        retrofitModule,
        if(BuildConfig.NEW_FEATURE_ENABLED) updatedModule else oldModule
    )
}

Then we aggregate together these various module lists to configure Koin.
